After being linked to a number of physical altercations, Brown was mandated to spend 90 days in a rehabilitation center where he first sought treatment for his issues last year. Although he has completed his 90 day sentence, E! News is reporting that a judge may be requesting that he receive additional treatment.

While Brown's representatives have yet to confirm or deny the reports, the singer took to Twitter to express his feelings concerning negative thoughts.

"Thinking negatively only ensures more negativity in your life," he tweeted. "It's ok to be upset and get angry. It's what u do with that energy that helps."

The singer's angry behavior made national headlines after he physically assaulted ex-girlfriend and singer Rihanna in 2009. Since that assault, Brown has made headlines for allegedly engaging in other physical altercations, including those with fellow entertainers Frank Ocean and Drake.

Despite his legal issues, Brown seems to be remaining positive on Twitter lately. Since 2014, it seems Brown has been focused on tweeting a more positive message following a year when he seemed to lash out on the social networking website on countless occasions.

"We can't control other people," he tweeted recently. "We only can control ourselves."

Brown reportedly entered rehab last year to gain better insight into his behavior.

"Chris Brown has elected to enter a rehab facility," Brown's representative previously told E! News. "His goal is to gain focus and insight into his past and recent behavior, enabling him to continue the pursuit of his life and his career from a healthier vantage point."

Brown gave millions of fans some insight into his thoughts about entering rehab right after beginning his stint last year.

"In order to go where u have never gone u have to be willing to go where u never been," Brown tweeted following the announcement that he would be seeking professional help.
